We investigate the light-quark mass and spatial volume dependence of matrix elements of ∆B = 2 and ∆C = 2 four-fermion operators. These operators are relevant for B0 (s)−B¯0 (s) and D0−D¯ 0 mixing in and beyond the Standard Model. An important conclusion of this work is that the chiral extrapolations for matrix elements of heavy-light meson mixing beyond the Standard Model are more complicated than that for the Standard Model mixing matrix elements.
